Después de los ensayos anteriores, de los que se hace un análisis histórico, de definir la diversidad de la vegetación gallega se propone una nueva ordenación basada en criterios actuales (florísticos, sucesionales, corológicos, respecto al Código de Nomenclatura Fitosociológica). El análisis se limita, en este caso, a las comunidades leñosas comprendidas en las clases Alnetea glutinosae, Calluno-Ulicetea, Cisto-Lavanduletea, Cytisetea scopario-striati, Pino-Juniperetea, Quercetea ilicis, Querco-Fagetea, Rhamno-Prunetea, Salicetea purpureae y Vaccinio-Piceetea, con un total de 65 asociaciones. Cada clase lleva una pequeña descripción que incluye su distribución en el territorio, las especies representativas y un comentario de sus afinidades con otras clases. Tras cada asociación aceptada se relacionan las tablas o grupos de inventarios gallegos que se asimilan a la misma con indicación del nombre originalmente osado y la referencia bibliográfica correspondiente.

The present article analyses the preferences of the deaf who use sign language and are users of the TV interpretation service to sign language, as well as the characteristics with which TV channels provide that service in television in Spain. The objective is to establish whether the way in which the aforementioned accessibility service is provided matches the preferences of users or differ from them. The analysis presents the opinion on this service of the deaf that use the Spanish sign language as their first language for communication. A study has also been conducted on the programmes broadcast with sign language during week 10-16/03/2014. The main data collected reveal that the deaf are dissatisfied with broadcasting times. They ask for news programmes with sign language, they would rather have the interpretation carried out by deaf people who use sign language and they prefer that the interpreter is the main image on screen. Concerning the analysis of the programmes broadcast, the study shows that the majority of programmes with sign language are broadcast at night, they are entertainment programmes, the interpretation is carried out by hearing people who use sign language and that their image is displayed in a corner of the screen.

Los cambios sufridos por los modelos de comunicación científica hacen que las bibliotecas universitarias se vean obligadas a dar nuevos servicios. Para adecuarse al investigador los bibliotecarios están desarrollando habilidades, colaborando con cada vez más estamentos y sustentando el acceso abierto. Apoyándose en una lista de posibles servicios, basada en la literatura especializada, este trabajo pretende cuantificar y evaluar el apoyo a la investigación desde las bibliotecas universitarias españolas. El sondeo demuestra la aparición de nuevos servicios e infraestructuras. Pero estas asistencias no suelen sistematizarse, difundirse ni evaluarse. Y, por otra parte, las consecuentes inversiones en personal y TIC han generado una brecha entre universidades

The first general survey of the history of women in early modern Ireland. Based on an impressive range of source material, it presents the results of original research into women’s lives and experiences in Ireland from 1500 to 1800. This was a time of considerable change in Ireland as English colonisation, religious reform and urbanisation transformed society on the island. Gaelic society based on dynastic lordships and Brehon Law gave way to an anglicised and centralised form of government and an English legal system.

This paper aims to demonstrate how in the constitutional rule of law the right of resistance plays a key role in its development, its adaptation to the changing reality of society and the satisfaction of the interests of all the people involved in this common project. Firstly, we will analyze how individuals or social groups must act when they suffer injustices due to state acts or laws that violate their most basic rights. In some cases, we believe that they have the right to exercise any form of weak resistance that they deem appropriate to present at the public scene a cause that must be socially and politically recognized. Secondly, we will see what happens when the rule of law itself is in danger. In that case, we believe that society will have not only the right but the duty to exercise the resistance in its most extreme form to defend the existing constitutional order of any illegitimate authority that seeks to impose itself on it and the sovereignty of the people.

The transition from a positivist matrix to an idealistic one in Argentinean academic philosophy can be read as a result of a gradual and problematic pollution. It was, also, heavily traversed by considerations that exceeded the theoretical aspects. Based on the willingness to explore this transit, the article pays attention to one of the episodes of this contamination: how the Revista de Filosofía reads Croce and Gentile’s philosophy. Observing there some possibility of dialogue between positivist assumptions, with which the journal takes a position, and the idealism the article analyze how this dialogue and its limits were given from a political consideration. If the idealism was condemned, it is centrally owed to its performance during the first years of the government of Mussolini. If, meanwhile, it was some to rescue of that philosophy, it was that it contributed to think the revolutionary change.
